Washington (dpa) - After riots in numerous American cities, US President Donald Trump has called for democratic mayors and governors to take a crackdown.

"Take a harder pace," Trump wrote on Twitter on Sunday. «These people are anarchists. Call our National Guard now. The world watches and laughs at you and Sleepy Joe. » Republican Trump denigrates his prospective challenger in the November election, Democratic ex-Vice President Joe Biden, as "Sleepy Joe".

The protests, which continued in numerous cities on Sunday, are the death of African American George Floyd after a brutal police operation in Minneapolis, Minnesota. The National Guard has been mobilized in Minnesota and in several other states after demonstrations have turned into riots and looting. The National Guard is part of the US Armed Forces Reserve and can be called for help in exceptional situations in states. In Minneapolis, the authorities extended the night curfew, which will come into effect on Sunday evening at 8:00 p.m. (local time).

Trump repeatedly accuses the Democrats of not being tough enough against crime. Trump blames left-wing radicals and Antifa for the recent riots. He has not presented any evidence of this. The president announced on Sunday that Antifa should be classified as a terrorist organization in the United States. He left details open at first.
